The Manning formula, also known as Manning's equation, is an empirical formula used to estimate the average velocity of a liquid in an open channel flow or in partially full conduits. This formula, first presented by the French engineer Philippe Gaspard Gauckler and later redeveloped by the Irish engineer Robert Manning, is essential for calculating flow variables in locations where constructing a weir or flume to measure flow is not practical. The formula is expressed as V = (k/n) * Rh^(2/3) * S^(1/2), where V represents the cross-sectional average velocity, n is the Gauckler–Manning coefficient, Rh is the hydraulic radius, S is the stream slope, and k is a conversion factor between SI and English units. The hydraulic radius, a property that controls water discharge and movement of sediment in a channel, is defined as the ratio of the channel's cross-sectional area of flow to its wetted perimeter. The Gauckler–Manning coefficient, denoted as n, is an empirically derived coefficient dependent on various factors. This formula is widely used in hydraulic engineering for estimating flow velocity and channel efficiency.

Manning Sherwin (January 4, 1902 – July 26, 1974) was an American composer known for his significant contributions to musical theatre and films. Born in Philadelphia, he honed his musical talents at Columbia University before making a name for himself in the entertainment industry. One of his most enduring compositions, "A Nightingale Sang in Berkeley Square", is a timeless classic with lyrics by Eric Maschwitz, originally featured in New Faces in 1940. Additionally, his wartime hit "Who's Taking You Home Tonight?", with lyrics by Tommie Connor, showcased his versatility and talent in creating memorable melodies.Settling in Britain in 1938, Sherwin became an integral part of the musical scene, contributing to various productions such as Magyar Melody and Sitting Pretty. Despite the outbreak of war affecting some of his works, he persevered and achieved success with productions like Get A Load of This, Something in the Air, and Under the Counter. His musical prowess extended to British cinema, where he provided music for hit wartime comedy features like Miss London.Sherwin's legacy also includes successful musicals like The Kid from Stratford and Her Excellency, the latter being a joint composition with George Posford.

Manning Coles was the pen name of the British writing duo, Adelaide Frances Oke Manning (1891–1959) and Cyril Henry Coles (1899–1965), known for their spy thrillers during the 1940s to the 1960s. The main character in 26 of their books was Thomas Elphinstone Hambledon, an agent working for a department of the Foreign Office, often referred to as "MI5" in the novels. Manning and Coles, who were neighbors in East Meon, Hampshire, drew inspiration from their own experiences, with Coles having served in British Intelligence during both World Wars. Their early books had a realistic and serious tone, while their postwar works leaned towards lightheartedness and whimsy. In addition to spy thrillers, they also penned humorous novels about modern-day ghosts, some involving ghostly cousins named Charles and James Latimer. Coles' real-life experiences in British intelligence, including working behind German lines during World War I, greatly influenced their writing. The Tommy Hambledon series, which includes titles like "Drink to Yesterday" and "Night Train to Paris," remains popular among fans of espionage fiction. Apart from their spy novels, they also wrote ghost stories and a historical essay. Their works are available at various digital platforms and have left a lasting legacy in the literary world.
